[ALL STYLES] 2D Videogame Artist (pixel, vector, painted)

Hey guys, I'm a professional game artist looking to help you with your projects for indie prices.
I have experience with every 2D art style, from pixel art, vector art all the way to digitally painted work. I've worked with hundreds of developers and provided many different art services.

Pixel art sprites for a space shooter.

So, forgive my ignorance, very new to this, SO! GameSalad supports Sprites? Is there any restrictions? I am going have someone make me a couple sprite to up load into gamsalad, anything I should know? Much appreciated!
